Functional description IMU
IMU provides three internal sensors, which get information about the vehicles acceleration.
These are:
• lateral acceleration
• longitudinal acceleration
• yaw rate
The values are sent via Chassis Expansion Bus. It is the base information for most of the
chassis systems, such as Semi-Active Damping System or Electronic Brake Control Module.

SAS (Steering Angle Sensor)
The Steering Angle Sensor (SAS) may be used POA with a module
associated with the steering column, or may be mounted as a
standalone component in the lower end of the steering column. It will be
used to measure the angle and angle velocity of the vehicle steering
column, or driver intent steering angle.

DAB (Digital Audio Broadcasting)
Digital Audio Broadcasting is a digital technology for broadcasting radio stations. This
standard offers several benefits over existing analogue FM radio, such as higher-fidelity
audio, more stations in the same broadcast spectrum, and increased resistance to noise,
multipath, fading, and co-channel interference.
The DAB Module is equipped in order to receive digital radio stations. It is only available in
Uplevel CD Radios and Navis and only in Europe.
DAB is controlled by the Radio.
